For example, outlets with outlet covers, or things that might be strangulation risks, such as headphones or cords? I admit that yes, I let him touch all of these things when I am supervising, even the portable heater...that is not turned on, of course. But, I'm wondering if this will send him mixed messages when I have to deny him in the future for safety reasons. What do you think? How shall I go about this? Methinks I've given him too much freedom and it will be hard if/when I have to take it away!
